FLAC Metadata and Tag Viewer
Drop in a FLAC file to read its stream details and tags: sample rate, channel count, bit depth, exact duration, total samples and the Vorbis comments such as title, artist, album, date and genre. The file is decoded entirely in your browser and never leaves your device.
How to view FLAC metadata
- Drag a .flac file onto the box, or click to browse for one.
- Read the sample rate, channels, bit depth and duration that appear instantly.
- Scroll to the tags section to see the title, artist, album and other Vorbis comments.

Frequently asked questions
Is my FLAC file uploaded anywhere?
No. The file is read and decoded entirely in your browser using JavaScript. Nothing is sent to a server, so your audio stays on your device.
How does it read the metadata in the browser?
FLAC files begin with a fLaC marker followed by metadata blocks. The tool parses the STREAMINFO block for the sample rate, channels, bit depth and length, and the Vorbis comment block for tags, all locally in JavaScript.
Which fields can it show?
From STREAMINFO it shows sample rate, channel count, bit depth, total samples and duration, plus the audio MD5 when present. From the Vorbis comments it lists tags like title, artist, album, date and genre.
How is the duration calculated?
Duration is the total sample count divided by the sample rate, both read from the STREAMINFO block. A 44100 Hz file with 44100 samples is exactly one second long.
Does it work with other audio formats?
This viewer is built for FLAC and validates the fLaC marker first. For other formats, identify the file type first and use a matching metadata tool.
